US20090201190A1-20090813.XMLThe U.S. Government has a paid-up license in this invention and the right in limited circumstances to require the patent owner to license others on reasonable terms as provided for by the terms of Prime Contract No. DTFA03-99-D-00017/0018, awarded by the Federal Aviation Administration (FAA) to The Titan Corporation, and as provided for by the terms of Subcontract No. 04-526 between The Titan Corporation and Patriot Technologies, LLC. None None 1. Field of the Invention The present invention relates generally to a system and method for providing perimeter security and, more specifically to a system and method for providing entry-point, boundary-line, and presence intrusion detection by means of an intelligent controller process capable of driving both field alert/alarm systems and security station monitoring devices. The system and method of the present invention is particularly applicable to use at airports but can also can be applied to perimeter security and presence-detecting security generally, including critical infrastructures such as chemical manufacturing plants, nuclear and non-nuclear power generation facilities, water purification plants, fuel storage installations, food processing plants, dams, and ports. The present invention more specifically relates to a runway occupancy warning system (ROWS™) providing critical runway status alerts to both flight crew approaching an airfield and air traffic controllers managing ground traffic. The preferred components of a runway occupancy warning system include: a detection system consisting of one or more D-hubs, airfield output devices (including all FAROS, GAROS and CTAF Runway Occupancy Radio Signal (RORS)), an airfield communications network, and a runway operations processing electronics unit (“ROPE”). 2. Description of the Related Art Among the sensor technologies in use today for detecting target position information on airport runways is a radar-based surveillance system that is being used to help controllers monitor movement of aircraft and ground vehicles on the airport surface during low or no visibility conditions. The ASDE-equipped airports represent the busiest airports with predominantly commercial air traffic and the most complex runway configurations. AMASS is a software/hardware enhancement for the ASDE-3 radar system designed to assist air traffic controllers in the safe movement of aircraft by providing safety warnings and alerts of potential runway collisions. AMASS builds on the ASDE-3 radar information by providing visual data (identity) information and audible warning systems to alert air traffic controllers that a runway incursion is pending. To meet surveillance needs at small to medium-sized airports, a new system, ASDE-X, was developed and has been contracted to be deployed at 25 additional airports. ASDE-X consists of a radar, a processor, non-radar sensors, and a display. It is designed to more precisely identify aircraft and vehicles on the ground than radar alone. ASDE-X was intended to provide a low-cost, scaled down feature set alternative to the ASDE-3/AMASS full surveillance system. As part of the FAA\'s strategy to improve safety and U.S. airports, the agency initiated a collaborative movement with other members of the aviation industry to implement improvements in capacity and efficiency to meet future air traffic demand over the next decade. In the plan, the FAA identified 35 airports that best represent the goals of the Operational Evaluation Program (OEP) plan as the primary drivers of NAS performance in terms of system capacity. It is these OEP-35 airports that are being targeted for capacity improvements as implemented by the FAA for high-capacity commercial airports. Each of the OEP-35 airports already has installed, or is scheduled to have installed, an ASDE-3/AMASS or ASDE-X system. The objective of the Airport Surface Detection Program is to design and deploy the ASDE-X surface surveillance system. The ASDE-X is a modular surface surveillance system that can process radar, multilateration and Automatic Dependent Surveillance-Broadcast (ADS-B) sensor data, which provides seamless airport surveillance to air traffic controllers. The ASDE-X system is targeted for second-tier airports and a Product Improvement/Upgrade for ASDE-3 Airport Movement Area Safety System airports. The FAA announced in June 2000 that the ASDE-X program would deploy 25 operational systems and 4 support systems. Additionally the ASDE-X Product Improvement/Upgrade for ASDE-3 sites will be deployed at 9 operational ASDE-3 sites, for a total of 34 operational systems and 4 support systems. The goal of ASDE-X is to increase airport safety through enhanced air traffic control situational awareness. The ASDE-X conflict-detection equipment (with multilateration) provides detailed coverage of runways and taxiways, and alerts air traffic controller (visually and audibly) to potential collision alerts. The system depicts aircraft and vehicle positions using identification overlays on a color map showing the surface movement area and arrival corridors. ASDE-X is an all-weather airport management system that provides aircraft location and identification to air traffic controllers. The system uses a combination of surface movement radar and transponder multilateration sensors to display aircraft position labeled with flight call-signs on an ATC tower display. The ASDE-X system provides fusion of multiple surveillance sources to support:
